Title: Waveform shaping circuit
Inventor: TAKAHASHI JUN
IPC: H04L25/06
Filed: 1989-02-16
Abstract: PURPOSE:To decrease the transient fluctuation of an integration circuit at an intermittent operation by attenuating an input signal with the integration circuit whose time constant is set small and applying its output to a capacitor of the integration circuit whose time constant is set larger so as to charge up the capacitor quickly. CONSTITUTION:Power is applied to a waveform shaping circuit and the waveform shaping circuit is operated for a period between t1 and t4 as shown in figure. A control signal for rapid charging is applied for a period from the time t1 to the time t2 in synchronism with an intermittent reception signal. In this case, an input waveform at an input terminal 2 is as shown by A in figure. The level of a waveform at a connecting point P1 of an integration circuit 11 rises from a zero level and the input signal is integrated. The level of the output of the circuit 11 is attenuated from the input level based on the frequency characteristic of the circuit 11. Since a level of the point P1 of the circuit 11 charges up a capacitor 6 through a differential amplifier 12 being a rapid charging buffer circuit, a waveform at a point P2 for the charging period is as shown in B. The waveform at a point P2 at the time t2 decreases along a discharge curve as shown by C in figure.

Title: Brushless motor
Inventor: HASHIMOTO AKIRA
IPC: H02K29/00
Filed: 1994-03-08
Abstract: PURPOSE:To increase torque to be generated from a motor by inclining the facing part of at least one of rotor or stator against the axial direction of rotary shaft thereby increasing the area facing a rotor magnet. CONSTITUTION:The stator yoke 8a of a motor is substantially tapered by flattening the ridge on the rotor magnet side and laminating yokes having gradually increasing hole. The tapered rotor magnet 5a is magnetized vertically to the tapered surface in order to facilitate formation of a magnetic path having shortest distance in the gap between the rotor magnet 5a and the stator yoke 8a. When the number of slots is increased and the cross-sectional area of the stator yoke itself is decreased or the sectral surface facing the rotor can not be enlarged in the peripheral direction, the area facing the rotor magnet can be increased by tapering the rotor magnet and the magnetomotive force is used effectively. This structure increases torque to be generated from the motor.

Title: Detecting circuit of bipolar signal
Inventor: TANIGUCHI TAICHI
IPC: H03M5/16
Filed: 1982-03-11
Abstract: PURPOSE:To output a fixed ''1'' level through the discrimination of the presence of a signal at pulse intervals of a bipolar signal is shorter than a time constant T assumed as a threshold value, and to output a fixed ''0'' level through the discrimination of the absence of signals when it is longer than the threshold value. CONSTITUTION:When the pulse interval of the bipolar signal is shorter than the time constant T, the 1st monostable multivibrator 2 is triggered with a unipolar pulse, the pulse of the other polarity passes through a logical product circuit 6 and is inputted to the 2nd monostable multivibrator 4 having a time constant 2T while the vibrator 2 keeps the ''1'' level for the time constant T, and an output terminal 103 is fixed to the ''1'' level representing the presence of signals. When the interval is longer than the T, since the pulse inputted from an input terminal 102 is inputted after the operation of the vibrator 2 is finished, the pulse is blocked at the circuit 6 and not inputted to the vibrator 4, then the output terminal 103 is fixed to the ''0'' level representing the absence of signals.

Abstract: PURPOSE: To check the coupling state and abnormality of vibrator correctly, by providing an element for detecting abnormality on a delaying material at a position symmetric to the vibrator for transmitting and receiving, being parallel to the material to be detected.  
     CONSTITUTION: An ultrasonic probe contacts with the material being detected 8 by way of a coupling shoe 6 and a contact medium 7, and the ultrasonic wave from a transmitting/receiving ultrasonic vibrator 2 passes through a delaying material 1 and runs through the delaying material 1 again at point (X) to be divided into the reflected component (BK echo) to an ultrasonic vibrator for abnormality detection 3 and the transmitted component to the medium 7. Passing through the medium 7 and then running again through the medium 7 at point (Y), the wave is divided into the reflected component (S echo) to the vibrator 3 and the transmitted component to pass through the material being detected 8, and then reflected at a defect 9 to return to the vibrator 2. In the diagram, a refers to BK echo, h 1  represents the level, which, when lowered, detects the abnormality of the vibrator 2, whereas b shows S echo and h 2  represents the level, which, when lowered, detects the abnormality in the coupling between the probe and the material being detected 8.

Abstract: PURPOSE:To enable ejection of required quantity of liquid with desired pressure by arranging a liquid ejection valve at the operating section of an endoscope then leading the pressure in an air piping into a pressure converter and pressure feeding the liquid toward an ejection port. CONSTITUTION:When an operational button 31a for a liquid ejection valve 31 arranged in an operating section 1 is depressed, a liquid flow-out path 32 is communicated with a liquid flow-in path 33 while communication between a pump side piping 17a and a valve side piping 17b of an air piping 17 is interrupted and an air pump 16 is blocked from the atmosphere to increase the pressure in an air piping 50, and a signal is fed from a pressure detector 4 to a valve control section 55 when the pressure in the air piping 50 reaches to a predetermined level. Consequently, a direction changeover valve 51 is switched to communicate a pressure lead-in pipe with the air piping 50, and thereby pressure is fed from the air pump 16 to the primary chamber 42 of a pressure converter 41 to boost the pressure in the secondary pressure chamber 43 thus ejecting high pressure liquid through an ejection port 30.

Title: Control circuit for gate turn off thyristor
Inventor: WATANABE JIYUNICHI
IPC: B25B13/56
Filed: 1981-03-18
Abstract: PURPOSE:To simplify an insulation between a main circuit and a control circuit by a method wherein an LC resonance circuit is connected to a gate and an auxiliary optical thyristor AOTh is connected to the gate. CONSTITUTION:When AOTh1 is turned ON with a pulse signal on AOTh1, an anode voltage on a thyristor GTO is applied through the AOTh1 to charge a capacitance C and when it exceeds a control voltage on Zenor diode ZD, a gate current is applied to GTO to turn ON the GTO. In this case, the potential on the gate and chthode is retained at the same level substantially and the AOTh1 extinguishes by itself. Subsequently, the AOTh2 is turned ON with a pulse from LED2, the charge of the C is applied through the AOTh1 to a reactor L and the counter resonance current becomes an extinction current of GTO to perform an extinction for the GTO. According to such a constitution, the AOTh has a reduced current capacitance, further since the C and L don't perform a direct communication for main circuit current, the ATOh also can be operated at a considerably small capacitance, at a high speed and the insulation between the main circuit and control circuit can be achieved very easily.
